Embodiment Construction

[0011] See figure 1 , shows an elastic limit mechanism, its structure includes: retaining ring, upper shell, lower shell, large end cap, small end cap, switch position swing block, guide rod, spring, steel ball, light-transmitting cover , lights and other parts.

[0012] Such as figure 1 As shown: the upper housing 5 and the lower housing 12 are fixed by M3 screws and M3 nuts. The first guide rod 6 and the second guide rod 7 are vertically installed inside the upper casing, and grooves are provided on the guide rods. Two steel balls 9 are horizontally installed inside the upper casing, and a spring 8 is arranged between the two steel balls. support. When the guide rod moves vertically, the steel ball and the groove of the guide rod move relative to each other. When the steel ball enters the groove, with the help of the spring force, the steel ball and the groove are closely matched to play a position-limiting role. The upper end surface of the first guide rod 6 fixes the t...

Abstract

The invention relates to an elastic limit mechanism, which includes a housing, which is characterized in that two guide rods are vertically installed inside the housing, grooves are provided on the two guide rods, and two limit steel bars are arranged inside the housing. The ball is matched with the grooves of the two guide rods, a spring is installed between the two limit steel balls, the upper ends of the two guide rods are respectively provided with end covers, and the lower ends of the two guide rods are respectively connected with the switch position swing block. connect. During the movement of the guide rod, the switch position swing block swings accordingly. The toggle switch is installed on the lower housing, and the switch handle is placed inside the switch position swing block. When the switch position swing block swings, the position of the toggle switch handle is converted. At the same time, the switch position swing block also plays the role of limit. The invention has the advantages of simple structure, convenient and fast operation. The pressing surface of the elastic limit mechanism is provided with a protective retaining ring to prevent misoperation and improve the safety of operation. An indicator light is provided in the elastic limit mechanism to realize the operation requirements of the switch under different light environment conditions.

Description

technical field [0001] The invention relates to the improvement of a switch, in particular to an elastic limit mechanism, which is used to change the operation form of a toggle switch from a toggle type to a push type. technical background [0002] The handle of the toggle switch is short, and it is difficult for the operator to pull it; the toggle switch has no design to prevent misoperation, and it is easy to cause misoperation of the switch during actual use; in addition, the operator cannot clearly identify the position of the switch in a dark environment state. Therefore, it is urgent to improve the existing toggle switch operation form, and at the same time, it can indicate the position state of the switch. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the toggle switch in the prior art, and provide an elastic limit mechanism, which changes the operation mode of the toggle switch from the...
